I've just bought an Ipevo VZ-X document camera and I've some hard times to
have it running with my Linux Box (a dell precision m6800 running Fedora

We've been using older USB-only Ipevo document cameras for several years
with no problems.
When it is recognized dmesg says:

Do an "ls -l /dev/video*" before plugging it in and then again after
it's recognized to see if any devices are getting created.
What is the output of "lsusb -v" when it's recognized.
Also use journalctl instead of raw dmesg to get more info and to see if
any services are picking it up.
In the remaining cases, I get from dmesg:
[32124.861677] Code: Bad RIP value.
[32127.116392] usb 3-1: new full-speed USB device number 122 using

Have you tried other USB ports? Do you have a USB hub you could try?
Maybe a different USB cable as well.
When connected via wifi, I can access it through its web configurator and I
can test its functionality but only on the browser (chrome) still it
doesn't
show up in any other application.
Unfortunately you can't access an IP camera through the usual video
interfaces. But you should be able to get vlc or mplayer to show it.
Ipevo provides a version of its visualization software for linux (ubuntu)
https://ipevo-api-cms.s3-us-west-1.amazonaws.com/software/visualizer/download/Linux/Visualizer_linux_1.0.5.33.zip
That's a last resort. :-) And won't work anyway if the device isn't
even connecting.
